PM2.5 samples were collected from six types of industrial parks in the Guanzhong region of Shaanxi Province, including cement/concrete, brick/construction materials, forging/metallurgy, thermal power, chemical production, and glass/ceramics. The carbon fractions, water-soluble ions, elements, as well as oxidative potential (OP) of PM2.5samples were analyzed to investigate the emission characteristics of different industrial sources and the relationships between PM2.5 chemical components and OP. The results showed significant differences in PM2.5 concentrations among the industrial parks, with brick/construction materials presenting the highest level (95.2μg/m3). The OC/EC (organic carbon/elemental carbon) ratio in brick/construction materials (5.5) was higher than those in other industries. Cement and concrete industry exhibited the highest Ca2+ concentrations. Elemental analysis showed elevated proportions of V in metal forging. Correlation analysis demonstrated significant positive relationships between OP and inorganic ions (SO42-、NO3-、NH4+) as well as metallic elements (Ca, Al, Cd, Cu). This study provides a scientific basis for identifying the source markers across common industries and for assessing their impacts on atmospheric oxidation capacity and human health.

采集了陕西关中地区6类工业园区(水泥混凝土、砖厂建材、锻造冶金、热电、化学品生产和玻璃陶瓷)的PM2.5样品,分析了其碳组分、水溶性离子、金属元素和氧化潜势,探究不同工业源的排放特征及PM2.5各化学组分与氧化潜势的关系.结果表明,不同工业园区PM2.5浓度差异显著,砖厂建材最高(95.2μg/m3);砖厂建材的OC/EC(有机碳/无机碳)比值(5.5)高于其他行业;水泥混凝土Ca2+浓度高于其他行业;锻造冶金行业V占比突出;PM2.5中无机离子(SO42-、NO3-、NH4+)及部分金属元素(Ca、Al、Cd、Cu)与氧化潜势呈显著正相关.本研究为确定常见工业行业PM2.5标识物及其对大气氧化性和人体健康的影响提供了依据.

采集了陕西关中地区6类工业园区(水泥混凝土、砖厂建材、锻造冶金、热电、化学品生产和玻璃陶瓷)的PM2.5样品,分析了其碳组分、水溶性离子、金属元素和氧化潜势,探究不同工业源的排放特征及PM2.5各化学组分与氧化潜势的关系.结果表明,不同工业园区PM2.5浓度差异显著,砖厂建材最高(95.2μg/m3);砖厂建材的OC/EC(有机碳/无机碳)比值(5.5)高于其他行业;水泥混凝土Ca2+浓度高于其他行业;锻造冶金行业V占比突出;PM2.5中无机离子(SO42-、NO3-、NH4+)及部分金属元素(Ca、Al、Cd、Cu)与氧化潜势呈显著正相关.本研究为确定常见工业行业PM2.5标识物及其对大气氧化性和人体健康的影响提供了依据.

PM2.5 samples were collected from six types of industrial parks in the Guanzhong region of Shaanxi Province, including cement/concrete, brick/construction materials, forging/metallurgy, thermal power, chemical production, and glass/ceramics. The carbon fractions, water-soluble ions, elements, as well as oxidative potential (OP) of PM2.5samples were analyzed to investigate the emission characteristics of different industrial sources and the relationships between PM2.5 chemical components and OP. The results showed significant differences in PM2.5 concentrations among the industrial parks, with brick/construction materials presenting the highest level (95.2μg/m3). The OC/EC (organic carbon/elemental carbon) ratio in brick/construction materials (5.5) was higher than those in other industries. Cement and concrete industry exhibited the highest Ca2+ concentrations. Elemental analysis showed elevated proportions of V in metal forging. Correlation analysis demonstrated significant positive relationships between OP and inorganic ions (SO42-、NO3-、NH4+) as well as metallic elements (Ca, Al, Cd, Cu). This study provides a scientific basis for identifying the source markers across common industries and for assessing their impacts on atmospheric oxidation capacity and human health.
